3!  Following are the routines contained within this MODULE:
4
5!  alloc_and_configure_domain        1. Allocate the space for a single domain (constants
6!                                       and null terminate pointers).
7!                                    2. Connect the domains as a linked list.
8!                                    3. Store all of the domain constants.
9!                                    4. CALL alloc_space_field.
10
11!  alloc_space_field                 1. Allocate space for the gridded data required for
12!                                       each domain.
13
14!  dealloc_space_domain              1. Reconnect linked list nodes since the current
15!                                       node is removed.
16!                                    2. CALL dealloc_space_field.
17!                                    3. Deallocate single domain.
18
19!  dealloc_space_field               1. Deallocate each of the fields for a particular
20!                                       domain.
21
22!  first_loc_integer                 1. Find the first incidence of a particular
23!                                       domain identifier from an array of domain
24!                                       identifiers.

441!<DESCRIPTION>
442! Wrf_patch_domain is called as part of the process of initiating a new
443! domain.  Based on the global domain dimension information that is
444! passed in it computes the patch and memory dimensions on this
445! distributed-memory process for parallel compilation when DM_PARALLEL is
446! defined in configure.wrf.  In this case, it relies on an external
447! communications package-contributed routine, wrf_dm_patch_domain. For
448! non-parallel compiles, it returns the patch and memory dimensions based
449! on the entire domain. In either case, the memory dimensions will be
450! larger than the patch dimensions, since they allow for distributed
451! memory halo regions (DM_PARALLEL only) and for boundary regions around
452! the domain (used for idealized cases only).  The width of the boundary
453! regions to be accommodated is passed in as bdx and bdy.
454!
455! The bdy_mask argument is a four-dimensional logical array, each element
456! of which is set to true for any boundaries that this process's patch
457! contains (all four are true in the non-DM_PARALLEL case) and false
458! otherwise. The indices into the bdy_mask are defined in
459! frame/module_state_description.F. P_XSB corresponds boundary that
460! exists at the beginning of the X-dimension; ie. the western boundary;
461! P_XEB to the boundary that corresponds to the end of the X-dimension
462! (east). Likewise for Y (south and north respectively).
463!
464! The correspondence of the first, second, and third dimension of each
465! set (domain, memory, and patch) with the coordinate axes of the model
466! domain is based on the setting of the variable model_data_order, which
467! comes into this routine through USE association of
468! module_driver_constants in the enclosing module of this routine,
469! module_domain.  Model_data_order is defined by the Registry, based on
470! the dimspec entries which associate dimension specifiers (e.g. 'k') in
471! the Registry with a coordinate axis and specify which dimension of the
472! arrays they represent. For WRF, the sd1 , ed1 , sp1 , ep1 , sm1 , and
473! em1 correspond to the starts and ends of the global, patch, and memory
474! dimensions in X; those with 2 specify Z (vertical); and those with 3
475! specify Y.  Note that the WRF convention is to overdimension to allow
476! for staggered fields so that sd<em>n</em>:ed<em>n</em> are the starts
477! and ends of the staggered domains in X.  The non-staggered grid runs
478! sd<em>n</em>:ed<em>n</em>-1. The extra row or column on the north or
479! east boundaries is not used for non-staggered fields.
480!
481! The domdesc and parent_domdesc arguments are for external communication
482! packages (e.g. RSL) that establish and return to WRF integer handles
483! for referring to operations on domains.  These descriptors are not set
484! or used otherwise and they are opaque, which means they are never
485! accessed or modified in WRF; they are only only passed between calls to
486! the external package.

561! to pass a pointer to a domain structure, this call requires an interface

619
620!<DESCRIPTION>
621! This subroutine is used to allocate a domain data structure of
622! TYPE(DOMAIN) pointed to by the argument <em>grid</em>, link it into the
623! nested domain hierarchy, and set it's configuration information from
624! the appropriate settings in the WRF namelist file. Specifically, if the
625! domain being allocated and configured is nest, the <em>parent</em>
626! argument will point to the already existing domain data structure for
627! the parent domain and the <em>kid</em> argument will be set to an
628! integer indicating which child of the parent this grid will be (child
629! indices start at 1).  If this is the top-level domain, the parent and
630! kid arguments are ignored.  <b>WRF domains may have multiple children
631! but only ever have one parent.</b>
632!
633! The <em>domain_id</em> argument is the
634! integer handle by which this new domain will be referred; it comes from
635! the grid_id setting in the namelist, and these grid ids correspond to
636! the ordering of settings in the namelist, starting with 1 for the
637! top-level domain. The id of 1 always corresponds to the top-level
638! domain.  and these grid ids correspond to the ordering of settings in
639! the namelist, starting with 1 for the top-level domain.
640!
641! Model_data_order is provide by USE association of
642! module_driver_constants and is set from dimspec entries in the
643! Registry.
644!
645! The allocation of the TYPE(DOMAIN) itself occurs in this routine.
646! However, the numerous multi-dimensional arrays that make up the members
647! of the domain are allocated in the call to alloc_space_field, after
648! wrf_patch_domain has been called to determine the dimensions in memory
649! that should be allocated.  It bears noting here that arrays and code
650! that indexes these arrays are always global, regardless of how the
651! model is decomposed over patches. Thus, when arrays are allocated on a
652! given process, the start and end of an array dimension are the global
653! indices of the start and end of that process's subdomain.
654!
655! Configuration information for the domain (that is, information from the
656! namelist) is added by the call to <a href=med_add_config_info_to_grid.html>med_add_config_info_to_grid</a>, defined
657! in share/mediation_wrfmain.F.
